Bio-catalytic micro- and nanomotors self-propel by the enzymatic conversion of substrates into products. Despite the advances in the field, the fundamental aspects underlying enzyme-powered self-propulsion have rarely been studied. In this work, we select four enzymes (urease, acetylcholinesterase, glucose oxidase, and aldolase) to be attached on silica microcapsules and study how their turnover number and

During the XIIth International School on Organometallic Chemistry “Marcial Moreno Mañas” (ISOC MMM 2019) that was held from June 12th to 14th 2019 in Castellón, Giorgio Olivo won the oral presentation prize for his talk about “Supramolecular control of selectivity in C(sp3)-H oxidation”. Congratulations Giorgio!
At the 14th International Symposium on Macrocyclic and Supramolecular Chemistry (ISMSC) in Lecce (Italy) from 2-6 of June, Ernest won one of the Poster Prizes sponsored by IUPAC, for his poster on “Matryoshka-Like Supramolecular Structure That induce The Regioselective Functionalization of C60”. Congratulations Ernest!
Michela Milan won the Josep Castells awards from the Real Sociedad Española de Química, Catalan section (RSEQ-Cat) for the best PhD in Chemistry in 2018. She did her PhD in the QBIS-CAT group of the Institute of Computational Chemistry and Catalysis (IQCC) under the supervision of Dr. Miquel Costas and Dr. Massimo Bietti about “Oxidation
We report a combined experimental–theoretical study on the 31P NMR chemical shift for a number of trans-platinum(II) complexes. Validity and reliability of the 31P NMR chemical shift calculations are examined by comparing with the experimental data. A successful computational protocol for the accurate prediction of the 31P NMR chemical shifts was established for trans-[PtCl2(dma)PPh3] (dma
Terminal oxo complexes of late transition metals are frequently proposed reactive intermediates. However, they are scarcely known beyond Group?8. Using mass spectrometry, we prepared and characterized two such complexes: [(N4Py)CoIII(O)]+ (1) and [(N4Py)CoIV(O)]2+ (2). Infrared photodissociation spectroscopy revealed that the Co?O bond in 1 is rather strong, in accordance with its lack of chemical reactivity. On the contrary, 2 has a
Although the unusual structural, magnetic, electronic, and spin characteristics of manganocene has intrigued scientists for decades, a unified explanation and rationalization of its properties has not yet been provided. Results obtained by Multideterminantal Density Functional Theory (MD-DFT), Energy Decomposition Analysis (EDA), and Intrinsic Distortion Path (IDP) methodologies indicate how this uniqueness can be traced back
On May 9, 2019, the Universitat de Gironaconferred the Honorary Doctorate degree (Doctor Honoris Causa) of the university to Prof. Evert Jan Baerends (VU University Amsterdam) and biologist Prof. Sovan Lek (University Toulouse III). Prof. Baerends is of course well known in the field of chemistry, in particular for his contributions to density functional theory
We have derived a new set of magic numbers for metallic clusters whose last energy level of valence electrons is half-filled with same-spin electrons in the electronic structure of the jellium model. These numbers may become a powerful tool for finding stable high-spin molecules. The 2N2 + 2N + 1 with S = N +
Since 2015 the IQCC is organizing a Science Slam (first, second, third edition). Next week on Monday May 13 the IQCC organizes the fourth edition to show the most representative research projects of the Institute to a wide audience. The research carried out within each of the research teams of the IQCC will be briefly summarized by the PIs
